| 英文摘要 | a single molecular precursor, bis(sec-butoxy)aluminoxy-triethoxysilane, was used as aluminum source for the synthesis of mesoporous aluminosilicates with si/al ratios ranging from 1 to 10 under acidic conditions. aluminum can be stoichiometrically incorporated into the mesoporous materials at ph = 1.5. the mesoporous aluminosilicates synthesized with the single molecular precursor display larger unit cell parameter and pore diameter than that of the materials prepared with aluminum sulfate, aluminum nitrate, aluminum hydroxide, and aluminum isopropoxide as the aluminum sources. ir spectra of adsorbed pyridine and nh3-tpd showed that both bronsted acidic sites and lewis acid sites with medium strength are present in the materials. however, no direct relationship between the acidic properties and the content of aluminum was observed when the si/al ratios of the mesoporous aluminosilicates are lower than 10. |
